Prior approval drawings in Haringey

Prior approval drawings for a Haringey house set out a larger rear extension for the council's neighbour-impact check. In the latest year of returns Haringey refused 19 larger home extension notifications and granted 13, so the council turns down more than it grants. Our drawings are built to answer the objections that cause those refusals. Fixed quote after a free constraints check.

    How we work on prior approval drawings

    Seven steps from first call to approval.

    The same model cut through the middle: every floor, the stair, the chimney breasts, the new mansard, rear extension and basement in section
    Section through the model: every floor on one datum.

    1. Enquiry and constraints check

      We check the property against conservation areas, listed status, Article 4 directions, tree preservation orders, flood zone and planning history. We choose the right route and send a fixed quote.

    2. Measured survey

      We survey the house on one datum: rooms, levels, boundaries, drains, trees and the neighbours' windows that the 45° and 25° tests depend on.

    3. Design options

      We model the house in Revit and show you options in 3D and plan, with the planning strategy and the precedents in your street.

    4. Design frozen

      You choose an option in writing. Nothing changes after this without your say.

    5. Independent check

      A second chartered technologist checks every sheet against the council's validation checklist and the policy. A senior review signs it off before anything is submitted.

    6. Submission

      We prepare the forms, certificates, fee and documents and submit through the Planning Portal.

    7. Officer liaison

      We answer the planning officer and make any amendments within five working days, at no charge until approval.

    Free redraws until approval. Every drawing set is checked independently, and the checker is never the person who drew it.

    More refusals than consents in Haringey

    Haringey's latest government returns record 13 larger home extension prior approvals granted and 19 refused. Refusals outnumber consents on a route designed to be quick and light. That tells an owner that neighbour impact is taken seriously here and that a notification drawn at the limit of the permitted depth will be tested.

    Under the Order the officer's test is about the effect on adjoining premises, so the refusals most likely come from windows, boundaries and levels. We cannot see the council's reasons file by file, but we draw those three things first. The national limits are: 6 m (attached) / 8 m (detached), single storey, height max 4 m; not on article 2(3) land or an SSSI, with 42 days for the council to decide from a valid notification.

    No additional-storey notifications were decided in the period, with 0 granted and 0 refused, so a roof-raising scheme here needs a full application.

    Victorian terraces and the long thin garden

    38.9% of Haringey households live in a house, and 37.2% own their home. On a narrow terrace plot, a side return and a rear extension compete for the same ground. A terraced house here averaged £803,381 on the latest Land Registry figures and a semi £1,235,802.

    Domestic gardens make up about 26.6% of the borough's land in the national land-use dataset, which is why rear space is where owners look. We survey the plot, draw the rear wall as first built and test the extension against both neighbours' windows before suggesting a depth.

    Conservation areas and Article 4 directions

    The council publishes 33 conservation areas and 25 Article 4 directions. Conservation areas are excluded from the larger home extension route, and a direction can remove a permitted development right on the land it covers. We check each plot against the boundaries, not the postcode.

    Where the route is closed, a householder application is the fallback. Haringey decided 689 of them in its latest year and granted 90.3%, which is a better prospect than the notification record might suggest. Our planning drawings service covers it.

    The drawings we prepare

    The Order requires: Written description (depth beyond rear wall, max height, eaves height), site plan, addresses of adjoining premises, developer contact address. We prepare that set and add scaled plans, a rear elevation and a section through the nearest neighbour window. Because refusals here outnumber consents, we also add a plain-language statement of the neighbour relationship so the officer has the argument as well as the drawings.

    The site plan follows the same standard as our location and block plans. The council fee is £249, paid to the council, and our fee is fixed after the free check. A second technologist reads the set against the Order before submission, and if the council asks for amendments we redraw without charging again.

    Reading an objection before it is written

    The best preparation for a refusal-prone borough is to imagine the neighbour's letter before the notification goes in. Objections to rear extensions tend to cite one of three things: loss of daylight to a rear window, a wall that feels overbearing along the boundary, or a loss of privacy from a new window. The first two matter most for a single-storey rear extension, and both can be tested on paper.

    We test them on every Haringey job. The section through the neighbour's window shows the angle the extension takes against it, the elevation shows how high the eaves stand above their fence, and the plan shows the distance. If any of the three looks weak, we change the design before it is drawn up, not after the council has written back.

    Timing and what happens after submission

    After submission the council checks the notification is valid, writes to adjoining owners and occupiers, and then has the Order's period to decide. Our job in that window is to answer any query quickly, because officers working to a deadline often decide on the information in front of them.

    If the decision is yes, the council issues written notice and you can start. If it is no, we move at once to the householder application, reusing the survey and the plans so the delay is as short as it can be.

    If a shallower scheme would do

    Where a refusal is likely, the honest advice may be to draw less. A scheme a little shallower than the limit can avoid the objection entirely, and for most families the lost depth is a fraction of a room. We show both options side by side with the neighbour impact of each, so the decision is yours before anything is sent.

    For houses that fit ordinary limits, a Lawful Development Certificate is firmer evidence, and Haringey decided 396 of them in the same year. Neighbouring Hackney and Enfield read the same Order differently, and our Haringey area page lists everything else we draw here.
